I run a core facility for AFM techniques, biological medical applications. My research is focussed on in the interaction of platelets and cancer cells. Platelets support cancer cells in nearly ...

Friction at the atomic scale appears to depend on the speed at which two surfaces move past each other. This surprising behaviour was observed as the tip of an atomic force microscope (AFM) moves ...

Studying friction at the atomic scale is a challenge, surmountable in only the past few years. The NIST software simulates atomic force microscopy (AFM) using a molecular dynamics technique.

Using a combined Atomic Force Microscope (AFM) and Scanning Tunneling Microscope (STM), the researchers showed that friction along the surface of a quasicrystal in the direction of a periodic ...

For example, friction can sometimes vary periodically with the atomic lattice as an atomic force microscope (AFM) needle moves across a surface. Nanotribology is becoming increasingly important as ...

friction measurements, roughness measurements, et al. Flexible environmental conditions: Imaging in air, imaging in fluid, fluid cell with temperature control, fluid cell with perfusion chamber, etc.

An AFM image of a diamond surface is shown to the right*. The surfaces were chemically modified by adding a single layer of atoms to examine the effect of mass on the friction between two surfaces.

When an atomic force microscope (AFM) tip is scanned transversely across a multi-walled carbon nanotube, the amount of friction measured is twice as much as when the same tube is scanned ...

Their study was published in Physical Review Letters ("Dynamics of Atomic Stick-Slip Friction Examined with Atomic Force Microscopy and Atomistic Simulations at Overlapping Speeds"). Studying atomic ...
